To verify if post-ureteroscopy (URS) stenting is still necessary as a routine strategy, or if some cases can be treated without.
Between August 2004 and April 2005, 85 patients were admitted to the Urology Department at the Nephrology and Urology Center, Al-Thawra Hospital, Yemen with ureteric stones of different size and site. All were scheduled and treated by the ureteroscopy method. According to prospective pure randomization, 45 patients were left non-stented at the end of the operation (non-stented group), while 40 patients were left with stent (stented group).
The ages of the non-stented group ranged between 6-70 years (mean 34.36 +/- 15.53), while the size of the stones ranged between 5-20 mm (mean 8.4 +/- 3.1). They were 33 males and 12 females. Regarding the site, 26 stones were in the right, and 19 in the left ureter. In the stented group, the ages ranged between 14-70 years (mean 39.35 +/- 13.36), while the size of the stones ranged between 6-16 mm (mean 9.9 +/- 3.2). They were 34 males and 6 females. Twenty-five stones were in the right ureter, and 15 in the left. Success was 100% in the non-stented group, while it was 39 out of 40 in the stented group. The 2 groups were compared statistically for postoperative analgesia, color clearance of urine and hospital stay, and found significantly different. However, for operative time, the difference was insignificant.
When treating ureteric stones by ureteroscopy, postoperative stenting should not be used as routine, but should be limited to those with ureteric injury, bigger sizes and prolonged operative time. The non-stenting method decreases the need for postoperative analgesia, time of color clearance and hospital stay.
验证输尿管镜检查（URS）术后常规留置支架是否仍有必要，或者某些病例是否可以不进行留置。
2004年8月至2005年4月期间，也门萨那解放医院肾病与泌尿外科中心收治了85例不同大小和部位输尿管结石患者。所有患者均计划采用输尿管镜检查方法进行治疗。根据前瞻性单纯随机化原则，45例患者在手术结束时未留置支架（无支架组），而40例患者留置了支架（有支架组）。
无支架组患者年龄在6至70岁之间（平均34.36±15.53岁），结石大小在5至20毫米之间（平均8.4±3.1毫米）。其中男性33例，女性12例。结石位于右侧输尿管26例，左侧输尿管19例。有支架组患者年龄在14至70岁之间（平均39.35±13.36岁），结石大小在6至16毫米之间（平均9.9±3.2毫米）。其中男性34例，女性6例。右侧输尿管结石25例，左侧输尿管结石15例。无支架组成功率为100%，有支架组40例中有39例成功。对两组患者术后镇痛、尿液颜色转清情况和住院时间进行统计学比较，发现差异有统计学意义。然而，手术时间差异无统计学意义。
输尿管镜治疗输尿管结石时，术后不应常规留置支架，但应限于输尿管损伤、结石较大及手术时间较长的患者。无支架方法可减少术后镇痛需求、尿液颜色转清时间和住院时间。
